How do i fix a lego bionicle 7397 clock? it is the same as the 7387. the second hand is shuttering.

timex - an inexpensive watch - is not worth fixing. you didn't say how old it is, but likely it is time for you to give it up and get a new one. (they do wear out, you know.)

you can try this although it may not work with your movement: set the clock at 9 and then move the hands forward past the 12 position. count the strikes. move the hands backward to the 9 position and then advance forward to the 12 position. count the strikes. did the strikes increase by one? if so, keep doing the same thing until your get 12 strikes when you are on the 12. then you can move forward and set the correct time and have the correct # of strikes.

same problem here.. everytime i adjust the analog clock it moved but the digital clock dont so it means i can correct the analog but i cant correct the digital clock please help us..

Hello, a week ago the small second hand (not long chrono second hand) got stucked and my irony swatch just stop moving. Although the chronometer could be running if started... The small hand just didn't move.
I tried different tricks, like removing battery, pull out main wheel and use chrono buttons to reset arms. Etc.
Today I noticed that when turning the wheel backwards a couple of times (one or two hours back) the little hand moved one second back... Pushing wheel back to On possition made the small hand move forward one second and get stucked again.
Then I did this procedure a couple of times, at some point I turned the wheel back for a while (may be 5 full turns) and noticed the small hand moved more than one second (5, 10, 15 seconds backward)... when I noticed it was moving freely I pushed wheel to on position and noticed the small second hand was running normal.. I hope it works for some of you. Greettings from Canada

If the second hand of your watch isn't moving, but the watch is otherwise keeping time, you most likely have one of two problems. The simpler to fix problem is that the second hand might have come loose from the post onto which it's been fitted. It's a simple friction fit, and a watch technician would simply remove the watch movement from the case and very (very!) gently push down on the seconds hand to re-seat it. If that's the problem, that's all there is to the repair.

A second potential cause for this behavior could be that a speck of dust or crud has gotten into the gears that operate the seconds hand, preventing it from moving. This can easily happen when changing a battery--many watches tend to get somewhat of a buildup of crud where the watch back meets the case. Especially with screw back cases, the process of loosening the back also loosens the crud layer, making it easy for little bits to fall in. If you do have crud in your movement, you're a bit limited in what you can do. Unlike old-time mechanical movements, very few quartz movements are made to be disassembled and cleaned. Instead, a watch repairer may be able to blow some air (not compressed air from a can--that will probably wreck your movement) to try to clear the gears. If that doesn't work, there is a little device that some watchmakers have that runs your watch at about 50 time as fast as normal. Spinning the gears like that can sometimes generate enough force to clear a blocked gear train. I have done this to resurrect several watches whose hands were stuck. However, I was still able to see the "pulse" of the second hand on those watches, even if the hand itself never moved forward.

You will need to do a mechanical adjustment to the hand.
Loosen the hand nut and adjust the hand the tighten.

Hope this tip helps to solve your problems

My Father severed his apprentiship at Augusta Schatz in Triberg. Never move the hour hand only move the minute hand, I know it is lond winded but does not un seat the hour hand fixing. But most important NEVER move the hand backwards ONLY forwards as this goes against the workings of the movement.

If you are sure the hands are not touching as they pass, perhaps the minute hand and hour hand are binding together at the hub. Try this: Gently pull on the minute hand by gripping its hub with the nails of your finger and thumb. It should slide forward a little (or come off). Also the same for the hour hand, to ensure it is not binding on the face of the dial.
I don't know the particular clock, but if it has a SECONDS hand, this is often the one that needs to be freed.
If all the hands are free, all should be good. If it has a seconds hand and the clock stops when this hand is going "uphill", try a fresh battery. If this doesn't fix it, remove the seconds hand and use the clock without it. Or you could try to counterbalance the hand by adding a little weight to the opposite side... this could work, but as it increases the mass of the hand also, it still might be a problem.
Another way might be to shorten the seconds hand..!

Try setting the crown to position 2 - i.e. the position normally used to adjust the date.  Then use the top and bottom stopwatch buttons to adjust the minute hand and 1/10th hand respectively.
